As all knows inindustrial produce many things ,including Air Hose ,so the Air Hose Coupling useful .and use widey.
Nine serious violations include failing to have a point-of-operation guard on a press brake; overexposing employees to respirable crystalline silica while sandblasting; lack of engineering controls to reduce silica exposures below the permissible exposure limit; not running exhaust through a dust collection system; allowing dust to accumulate outside of the blast enclosure; failing to evaluate respiratory hazards; failing to conduct medical evaluations for workers using respirators; respirator couplings not being compatible with air hose couplings; failing to ensure surfaces were kept as free as possible of hexavalent chromium; and lack of hazard communication training. A serious violation occurs when there is substantial probability that death or serious physical harm could result from a hazard about which the employer knew or should have known.
One other-than-serious violation was cited for failing to sample employees expected to have the highest hexavalent chromium exposure levels. An other-than-serious violation is one that has a direct relationship to job safety and health, but probably would not cause death or serious physical harm.
Guillemin Symmetrical Clutch (France and Belgium)
Also known as a DSP, this type of hose coupling involves a “quarter turn” and “sexless” (symmetrical). A ring in each end with two protuberances outside; when the ring turns, the protuberances lock to the hook of the other hose. This type of hose coupling can be fastened by by hand, but it is also possible to use a tricoise wrench.
